Blue tint on mac wake from sleep

Alec Jacobson

If you wake your mac from sleep and suddenly your screen is all a slightly blueish hue. Open up Terminal.app and issue this command:

/System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/CoreGraphics.framework/Versions/A/Resources/DMProxy

Update: This also works if you screen gets a funny bluish tint when Powerpoint slideshow mode goes back and forth from fullscreen.
